编写程序,随机输入圆的半径和圆柱的高

#includemain(){\x09floatS(floatr);\x09floatr;\x09printf("inputr:");\x09scanf("%f",&r);\x09printf("圆面

#includeintmain(){floatr,s,l;scanf("%f",&r);s=3.14*r*r;l=2*3.14*r;printf("s=%f,l=%f\n",s,l);return0;

CLEARSETTALKOFFINPUT"请输入半径:"TORL=2*PI()*RS=PI()*R*R"半径为R的圆的周长为:",L"半径为R的圆的面积为:",SSETTALKON

importjava.util.Scanner;publicclassTest{publicstaticvoidmain(Stringagrs[]){Scannera=newScanner(Syste

voidmain(){floatr,s,l;floatpi=3.1415;printf("输入一个圆的半径:\n");scanf("%f",&r);if(

function[SV]=sphere(R)%定义函数S=pi*R^2;%求圆的面积V=4/3*pi*R^3;%求求的体积调用方法[ab]=sphere(1)

楼上的方法应该没错,可感觉对于表现java面向对象的特性没有表现出来,下面是我写的,应该非常清楚明了了importjava.io.BufferedReader;importjava.io.InputS

PrivateSubCommand1_Click()DimrAsSingleDimcAsSingleDimsAsSingler=Val(Text1.Text)c=2*3.14159*rs=3.1415

#include#definepai3.15149256voidmain(){doubler,c,s;printf("pleaseinputr\n")scanf("%lf",&r);printf("c

（法1）#includeusingnamespacestd;#definePI3.1415926classCircle{doubler;public:Circle(doubleR=0){r=R;}vo

VB?告诉你运算语句输入半径r高hS=2*π*r^2+2*π*r*h输出

ConstPI=3.14159DimrAsDoubleDimCAsDoubleDimSAsDoubleIfIsNumeric(Text1.Text)Thenr=Val(Text1.Text)C=2*P

第一段程序：m=pie*r*r,这句逻辑上有问题,m为输入值,r未赋值,默认0,for(i=1;i

packageex3001;importjava.util.Scanner;publicclassEx3001{publicstaticvoidmain(String[]args){doublex,y

#include"stdio.h"#definePI3.141592653//定义πintmain(void){floatC,A,V,r;printf("请输入半径：");//提示输入scanf("%

#...intr,b,dsin

如果是VB的话,小意思,我给你编辑,只要求选择我.

C编程求助编写一个基于对象的程序：输入半径,计算圆的周长和面积并输出实现#include

clearinput"请输入圆的半径："torl=2*pi()*rs=pi()*r*r?"周长是：",l?"面积是：",s
